Feathering

Feathering is a technique used in computer graphics software to smooth or blur the edges of a feature.

Feathering is most commonly used on a paintbrush tool in computer graphics software.

Feathering may also blend the edges of a selected feature into the background of the image.

The "Clone" tool is very important in photograph manipulation on computer graphics software.

This makes the pixels being copied have more effect on the area they are copied to closer to where the artist is dragging his or her mouse or stylus, and makes the pixels have less effect the farther they are from the clone tool (and where the artist is using it).
